The answers are: condense; visible
Explanation:
In Prophase I, the chromosomes condense and become visible.
Answer:I'm almost sure it's b or d hope this helped
Explanation:
Answer:
The correct answer is - 4 and 7 chromosomes in each cell.
Explanation:
Meiosis is the cell division in which one parent cell produces four daughter cells with a half number of the chromosome than parent cells.
According to the question oak cell performed meiosis which is reduction division so the number of cell will be four and 7 chromosome will be present in each daughter oak cell.
Thus, the correct answer is - 4 and 7 number of chromosome in each.
Answer:
A Ligase
B False
C To separate the double‑stranded DNA
Explanation:
The Polymerase Chain Reaction (PCR) is a technique widely used in molecular biology laboratories in order to make millions of copies of a specific sequence of DNA. PCR requires deoxynucleotide triphosphates (dNTPs) to synthesize new copies of the target DNA fragment, a thermostable DNA polymerase that adds nucleotides to new DNA strands, and primers that attach to complementary ends at each DNA strand. PCR has three phases: 1-Denaturation, where the double-stranded DNA molecule is heated to separate it into two single (separated) strands; 2-annealing, where the temperature is lowered in order to allow the primers to attach each DNA strand, and 3- extension, where the temperature is increased (again), and the thermostable DNA polymerase adds the appropriate dNTPs to new DNA strands. In consequence, annealing occurs at the lowest temperature. Moreover, during the denaturation stage, the temperature is increased at 90–95°C in order to denature the DNA strands into single strands.
